Best insulated: Klean Kanteen
After testing a multifariousness of sizes over the concluding three years, the best insulated bottle is from Klean Kanteen, either the 20-ounce wide rima oris if yous demand a compact canteen or the 32 ounce classic if you want to keep beverages common cold or hot all day long.
A smaller insulated canteen
The wide mouth of the 20-ounce made it piece of cake to fill up with ice and to beverage out of, and its slim design made information technology easy to fit in cupholders and bottle compartments in most backpacks. The wider rima oris is a slight compromise in insulation, but for a smaller bottle you might not notice the difference since you lot'll be refilling long before your ice is gone.
A Smaller Option
Klean Kanteen - 20-Ounce Insulated
A wide oral cavity, handy loop cap, good insulation properties and a clean pattern made the Klean Kanteen our acme pick. This rugged Kleen Kanteen likewise held up well when nosotros subjected it to our drop test.
The big loop lid makes information technology like shooting fish in a barrel to conduct with a few fingers or loop onto bags with a carabiner. If you lot don't care for this feature, wide mouth Klean Kanteen bottles tin can also have the totally leakproof Cafe Cap two.0 twist-open chapeau. We tested this design in our travel mug review. We liked it better than inexpensive flip-upwardly lids, though it's not every bit expert as other mugs for 1-hand sipping and has a lot of parts to clean.
This canteen fared well in our drib tests with minimal damage to both the bottom and the lid. In the insulation tests it ranked 2nd for cold h2o, and 3rd for hot h2o. One downside of any steel bottle is that the oral cavity gets hot to the bear on afterwards letting it bake in the car on a hot day.
A larger insulated bottle for all-day cold
The Klean Kanteen-Archetype 32-ounce is a great water bottle for storing and sipping ice-cold water without every bit many refills. The opening is about half an inch narrower than the broad mouth on Klean Kanteen's mug-size bottles, which means it's a little more catchy to pack with ice, but notwithstanding much easier than the wine-bottle shaped MIRA and Southward'WELL bottles.
Whether yous're filling with ice water or another beverage, this insulation volition proceed it cold (or hot) for longer than any wide-rima oris bottle. Klean Kanteen also sells this same bottle pattern with with a clamp-down growler lid for filling up at your favorite micro-brewery. (The Growler model besides works with the standard lid.)
Best glass: Takeya – Archetype
Our top choice for glass bottles was the Takeya Classic 22 ounce. We loved the large cap threads effectually the tiptop of the bottle, which makes information technology like shooting fish in a barrel to open and close the cap without missing the threads.
This bold and unproblematic design of the cap helps foreclose it from damage when dropped too. In our drop tests there was minimal cap impairment, and the silicone sleeve surprisingly prevented the bottle from shattering. The sleeve blueprint on this bottle makes it easy to encounter the remaining water levels too.
Best Drinking glass Option: Takeya - Classic
The Takeya's easy-to-apply cap features actress wide threads. This glass water bottle'due south clean design and high-quality materials get in stand out, plus the side viewing window is a fun touch that'southward besides functional.
Simply like the other glass bottles nosotros tested, at that place'southward no insulation, but there's too no lead or chemicals and information technology's completely dishwasher safe. However, this bottle's perfectly sized for easy holding and drinking, and the silicone grip makes it even more than secure if you're using it for sports.
Best Stainless Steel: Klean Kanteen – Classic
The Klean Kanteen was an piece of cake #1 option out of the 3 finalists. The oral fissure was much bigger, easier to fill with ice and water and more pleasant to drinkable from. It also had a cap with bigger threads to more easily open and shut the bottle.
Its lid was the best of the steel bottles we tested, simply a bit squeaky sounding and not as smooth in opening and closing as the insulated or glass bottles. For those who want options, this brand has many cap options y'all tin buy separately, like a sport cap or a sippy cap.
All-time Stainless Steel: Kleen Kanteen - Classic
Large cap threads, a mid-size and a polished design make the Kleen Kanteen - Classic a pleasure to potable from. This bottle also uses loftier-quality materials that make it seem more polished than our other contenders.
Yous also can't really appreciate the importance of the bottle'due south mouth size until you're trying to aim information technology under your fridge'due south h2o dispenser. Klean Kanteen sells a version of this canteen with a rima oris that'south fifty-fifty wider, simply the classic is noticeably wider than the other two bottles we tested. It'southward easy to sip from, but still easy for calculation ice, too. All iii stainless steel bottles are very basic products and similar in concept, but the Klean Kanteen is built with better materials and feels similar a more than polished product, making it our clear winner in this category.
Best plastic: Thermos – Intak
We loved the Thermos – Intak, ranking it our top plastic water bottle. The flip height chapeau and single-handed use were pretty big factors that helped set up this model apart. It's tough to beat out that convenience.
This bottle's the but ane that has a textured design built into the bottle to aid improve grip — great for when you're using this for sports since this bottle builds up condensation with cold h2o inside.
This bottle's the only ane that has a textured design congenital into the bottle to help improve grip — peachy for when you lot're using this for sports since this bottle builds up condensation with cold h2o within.
This bottle'south the simply 1 that has a textured pattern built into the bottle to aid improve grip — great for when you're using this for sports since this bottle builds up condensation with common cold water inside.
All-time Plastic Option: Thermos - Intak
The Intak comes with a flip top that get in like shooting fish in a barrel to utilise when you lot only have one had free. Its durability and a leak-proof design also helpe brand this bottle stand out from the contest.
Although all of the plastic bottles nosotros used had markings to measure liquids on the side, the Thermos has a unique ring built into the cap ranging from i-v so you lot can track how many times you lot've refilled or used the bottle throughout the twenty-four hours.
Best collapsible: Vapur – Chemical element
Our top pick was the Vapur – Element canteen. This bottle has a flip-pinnacle cap for easy access, but it also closes securely with an aural click and volition not pop off accidentally in your pocketbook. The Vapur and the Tap were the only two we tested with mouths wide enough for ice cubes and for a brush to fit inside for thorough cleaning.
Best Collapsible: Vapur - Chemical element
With a flip-top for 1-handed apply, the Vapur features a wide rima oris for easy cleaning or adding ice. Information technology'due south durable and made with quality materials. Nosotros also like its vibrant color options.
This was a 0.7L model, and you lot can get the most of that chapters past showtime blowing up the handbag to expand it before adding water. Materials and construction on this bottle are excellent and should last for many years of use. In addition, it'due south light weight and easily folded, which makes it bully for taking on runs, hikes, or stowing away into baggage or carryons when traveling.
Other insulated water bottles nosotros tested
The 25 oz. Mira bottle performed all-time in the common cold water test. It likely gets a bump in performance due to its relatively pocket-sized cap design — the primary surface area where there isn't vacuum insulation and where external temps would seep in.
The smaller opening of this bottle also comes with a downside though — it'south slightly bad-mannered to beverage out of since it'southward sized perfectly to striking your nose with each sip. In the hot water test, it was not a surprise that the Mira ranked second. The 25 oz. bottle we tested was a bit on the larger side for cupholders, so if you opt for Mira's 17 oz. bottle it would be a nicer fit.
Best for Sports: Under Armour - Dominate
With a 24-ounce capacity, a bound-based flip-top hat and comfortable silicone grip, this ane surprised us. We too liked its latch mechanism, just unfortunately it's intended only for cold beverages (not hot liquids).
As some other great option geared for sports, we liked the 24 oz. Under Armour bottle. It ranked 4th in our cold water test, just is past no ways a poor performer given its other perks. This bottle features a spring-loaded flip cap and silicone grip makes it easy for one-handed functioning while running or driving. It even has a latch to ensure the bottle stays locked during transport in your haversack or gym pocketbook. One downside is the manufacturer says this bottle can't be used with hot water, probable considering of the plastic components in the lid.
The SIGG Thermo performed best of the small bottles in our first hot water test, sadly, it'southward becoming hard to runway down. Specifically designed for tea drinkers, the SIGG has a congenital in metal filter, if you won't always use that feature y'all can remove it for hot water or coffee. You lot have to split up the lid by unscrewing it which is not every bit simple as it should be, simply it is an option. We looked at the larger versions in Sigg's Archetype series, but most owners agree they're better as a thermos (using the cup that slides over the base of operations of the bottle) than as a bottle to drink from.
Other glass water bottles nosotros tested
Too Nifty: Ello - xx-Ounce
The Ello features a simplified design, with lots of color options and different silicone sleeve designs to choose from. The silicone sleeve isn't but for looks — it also helped the Ello survive our impact tests.
We ranked the xx oz. Ello canteen in a shut 2nd identify, largely due to its simplicity. It gets the job washed without features that are prone to problems. Like the Takeya, it has large threads in the cap for piece of cake opening and endmost of the lid. Its large loop on the cap lets you carry the bottle with multiple fingers, distributing the weight for comfortable conveying for longer periods of time.
This cap design likewise helped spread the bear on nicely in our drop test that left no noticeable damage on the bottle. Similar the other glass options, we accept lots of options in silicone sleeve design and color too.
The little drinking spout on the Life Factory canteen might be convenient to some, just at that place was no other pigsty to let air in every bit you beverage from it, so y'all basically have to waterfall from the footling spout to take a sip. Although this bottle didn't leak in our tests, the mini spout cap is very prone to popping off and then you don't want to throw this into a bag that you tin can't keep an eye on.
The CamelBak' storable straw doesn't have issues with potential leaks because information technology is easily folded back when not in use. The uncentered design of the cap loop can bear on the outcome of a drop depending on how it happens to exist dropped, but in our testing it fared well. The CamelBak is a well-designed bottle overall that's like shooting fish in a barrel to utilise, but the harbinger makes it pretty difficult to ensure a proper cleaning, putting it further down on our listing.
It's hard for the short bKr bottle to become unnoticed — it looks very well designed! This one's basically famous for being used by celebrities and being covered in magazines. When we bought information technology, the cost was $35; this is an phenomenal 2-3x the toll of the other glass options. The slanted cap made screwing the cap on particularly difficult, and the small spout makes it incommunicable to fit any water ice or a bottle brush. The bKr bottle is definitely a blueprint-axial purchase if you're willing to put up with its issues and toll tag.
Other metal bottles we tested
The bottom of all of these bottles were dented in our drop test, which caused a few to wobble on the table. All the same, all remained leakproof afterwards. None of these were fabricated to insulate liquids, and all had condensation running down the outside. These are a good inexpensive route to go if yous just need to keep water cold for shorts amount of time.
The aluminum SIGG bottle is lightweight, simply it has a tiny cap and threads. This fabricated for a slightly clumsy opening and closing, and was the only bottle in this category that couldn't fit ice in the mouth unless it was crushed. The aluminum dented slightly on the lesser in our drop test just still sat perfectly flat on a tabular array. Even though it can't fit ice, this bottle felt a little more polished than the Cheeki bottle.
The Cheeki was the largest stainless steel bottle we tested, perhaps contributing to the amount it was dented in our driblet test. This bottle was noticeably uneven and even wobbled on the table after this test. Its oral fissure was big enough to fit ice cubes in, but the usage of the flip top lid is a fleck awkward because of its small size and poor design. In terms of quality of materials, this canteen was hands the worst when you examine the cap material, design, and loop material.
Other plastic h2o bottles nosotros tested
Also Dandy: CamelBak - Chute
The durable CamelBak - Chute is fabricated of shatterproof Tritan that aid it concord up against daily wear and tear. This plastic water bottle selection also features a one-piece tether that keeps the lid and cap attached to the canteen.
We loved the wait of the plastic CamelBak canteen and it proved to be very durable and leakproof. The spout has a cap that locks into the hat, which is a bit difficult to snap in each time, but information technology works to go along it out of the style. This bottle features a loop that keeps the hat attached to the canteen when you lot remove the lid for refilling likewise, something not present on the Embrava or Contigo or Thermos.
Although the the Embrava and the Contigo too had single-handed operation, the Embrava was slightly on the small side, with six ounces less capacity than the top ranking Thermos. Embrava'due south adjacent size upward is a whopping 32 ounce bottle, which is a flake on the big side. However, we appreciated the spout's added air vent in the cap for easier drinking. The flip cap was surprisingly strong in our drop examination too. If you prefer a slightly smaller bottle than the Thermos and can get past Embrava's design aesthetics, this was a close runner upwardly.
Both the CamelBak and the Nalgene had large threads for an easy opening lid and a wide rima oris for cleaning and adding ice. Notwithstanding, the Nalgene had pretty bad plastic smell, even after a few washes. It looks similar many other owners of this bottle had this result too, although many reported no smells. Perhaps they vary by canteen or manufacturing batch, but this factor, combined with a very cheap looking chapeau, pushed this canteen further down our list.
The Contigo Autoseal has a unique button y'all hold on the back to open the drinking spout. This bottle was leakproof when the button isn't held, but information technology'due south far likewise easy for that button to be pressed when thrown into a purse. Having to put your rima oris on the bottle proved to exist a footling weird, and nearly like a toddler'southward sippy loving cup, but it has an air valve and then you tin drink without having to waterfall.
These bottles are not for hot beverages. If you're looking for a hot beverage bottle accept a look at our vacuum insulated stainless steel pick above. All five bottles we tested were made of the copolyester, Tritan, which is a trademark of Eastman Chemic Company. This material is popular because it's impact resistant, free of BPAs, too equally estrogenic and androgenic action. Even so, every bottle we tested, including the collapsible plastic bottles, were made from BPA-free plastic.
Other collapsible water bottles we tested
Our second pick for collapsible bottles was the Tap, which was sold in a pack of two. Like the Vapur, it has high quality structure and has a wide mouth for ice cubes and for cleaning with a bottle brush. Cleaning is much harder without a wide rima oris since it wouldn't clean well in a dishwasher. This bottle has a carabiner for convenience, but is just pushed to second identify because lack of a convenient spout when compared to the Vapur.
The Aquabod is a unique canteen since you lot can coil information technology up, secure information technology, then stash in your gym bag or backpack until you're ready to use it. It'south also the only collapsible one we tested made of silicone. The canteen has a neat spout designed to limit how much h2o comes out, merely both the cap and the carabiner felt cheap compared to the others.
Although all these bottles take some flop to them when you drinkable, the Aquabod was extra floppy since there's less structure to it, forcing yous to use 2 hands to potable about of the time. The flop likewise makes it difficult (merely not impossible) to put this bottle into a backpack's bottle pocket, making clipping with the carabiner the way to go.
If you don't demand a carabiner, you might appreciate the Platypu' more than utilitarian design, and slim center for easier handling. Its mouth was as well small for ice or a cleaning brush, then you might have to boil it or exercise lots of manual shaking to get it clean. The merely reason to get with a Platypus is to utilize the push-pull cap option they have. For us, we would rather but become with the Tap bottle with a carabiner and wider rima oris.
All bottles had a slight smell — plastic or otherwise, earlier the beginning launder. You might have to launder it a few times or soak it in vinegar and h2o to go rid of most of the aroma and taste. If you're very sensitive to smells, you may want to consider another bottle material altogether.
Hydro Flask vs. Klean Kanteen
The 32 oz. Hydro Flask is a stiff runner-up. Hydro Flask ranked third in our cold h2o examination and 4th in the original hot water test, but they're a very close competitor for our top choice. The loop on the cap makes it piece of cake to pick up with one finger if your hands are full carrying other things and the grip on the cap makes it like shooting fish in a barrel to open and shut the chapeau.
We interviewed loyalists for each brand, and they all have glowing accounts of how great the bottles are. They too rave about how piece of cake it was to go a replacement cap or sometimes fifty-fifty a free replacement bottle afterwards a dramatic accident.
The biggest divergence between Klean Kanteen and Hydro Flask is in the availability of different neck shapes. Hydro Flask uses wide-rima oris openings for sizes from 18 to 64 ounces, with the narrower "standard" oral cavity is only available in 18, 21 and 14 ounce bottles. Klean Kanteen has almost the opposite selection, with their "archetype" narrow-mouth design available in sizes from 12 up to 64 ounces, with wide-mouth options in 12, 16 and 20 ounces.
Since the narrower mouth is better at insulating while all the same making water ice fairly easy to add, and the 32 ounce Klean Kanteen is more affordable, we retrieve Klean Kanteen has the border overall. If you're conveying a bottle packed with water ice for sipping cold water on a hot day, the temperature difference is going to be less important and you should feel free to buy whichever canteen has the cap and styling you prefer.
Both of these brands also makes a spectrum of durable powder-coat colors that should satisfy anyone, but the availability of your favorite colour might change from month to month. If you can't discover the colour you like in stock, information technology's probably worth checking the other brand.
What bottle type is best for you lot?
With all the different types of water bottles — plastic, metal, drinking glass, insulated or not — it can be confusing to choice the best 1 for your needs. In addition to our tiptop pick, we've identified iv runner-upwardly options to requite you lot plenty of choices to pick from, including a collapsible version.
Each canteen textile has its own strengths, and knowing the advantages of each volition help you observe a bottle y'all'll be happiest with. The only type of canteen to continue drinks hot or cold are vacuum insulated bottles. Every other type does not, and these other ones all grade condensation on the outside when you put cold water inside. Check out the breakdown below for more than differences:
Vacuum insulated bottles are the best fashion to continue your water super cold for an entire day, or to continue beverages hot for an impressive five hours. These insulated bottles have 2 inner chambers, 1 for the water and then 1 surrounding that with a vacuum channel. This proves to exist a very constructive method for insulation, merely these counterbalance more because of it.
Glass water bottles eliminate plastic or metal tastes and chemicals / BPAs. Being able to see how much liquid is left without having to pick up or open the bottle is a nice perk. All were covered in a silicone sleeve for driblet protection (no bottles cracked or shattered in our drop tests) only glass and silicone will non insulate your water. Condensation formed on all drinking glass and silicone surfaces even though the silicone sleeves helped amend grip.
Stainless steel bottles are an effective, low-toll option. They're non-reactive, BPA free, and lightweight compared to glass or their insulated stainless steel counterparts. You can't put hot water in these as directed by the manufacturers (and y'all'll burn your easily). But if y'all just need something for brusque amounts of time and don't intendance nearly insulation, information technology's tough to crush the value. Some folks adopt glass to avoid the metal odour or taste, but nosotros found no issue with tastes on these bottles at all. We also tested one aluminum bottle, which is a bit lighter only otherwise like.
Plastic water bottles are geared towards sports and workouts. Even if you're not using it for those purposes you can still benefit from their sporty design features. Three of the bottles we tested had a flip-top chapeau that lets you drink using one hand, which we loved. They're also lightweight compared to glass and insulated bottles. Every canteen we tested was made of Tritan, a material claiming to exist gratis of BPAs, estrogenic and androgenic activity. Nosotros still constitute these bottles to have the strongest scent though.
Collapsible water bottles are perfect if you lot're traveling or hiking and space is very limited. They are incredibly thin and the lightest weight option by a large margin — collapsible bottles nosotros tested weighed eight times less than insulated bottles, and four times less than our tested plastic bottles. These do have a olfactory property but generally go away after a few washes.
How we selected bottles to test
At that place are a lot of water canteen options out there, so we started past narrowing our list of finalists past only selecting those that fit specific criteria. There are many materials and styles these bottles are fabricated in, so we tested 5 of the near popular types.
We searched Amazon, Reddit, forums and other water bottle reviews to observe the highest quality and most popular brands of water bottles.
A review on Outside Online cited a SIGG bottle that outperformed anything nosotros've heard of in terms of thermoregulation, so we had to add that to the test list as well.
Every bottle we chose fit these criteria:
Water chapters: It held enough water to quench thirst, only information technology wasn't as well big that it would be cumbersome to lug around. Many brands have larger bottles at 32 and even 64 oz capacities.
They're well-reviewed: Other reviews that praised bottles, and bottles on Amazon's best-sellers listing were slightly favored.
Fewer issues with quality: Any bottles that have a higher than average history of complaints on build quality, leaking or other functional qualities were omitted.
They're not as well specialized: Nosotros avoided bottles that were designed for very specific tasks, such as cycling.
They're not knockoffs: Whether it'due south a knockoff or rebrand, many of these are really the same exact bottle then we didn't test duplicates. Come across more detail below.
Knock-off and rebranded water bottles
If you shop for water bottles online or in many retail stores, you'll detect many brands with products that look identical. For example, the Mira bottle we tested seems to accept the same pattern equally Uncomplicated Modern, ICONIQ, and the popular S'well to name a few.
The popular Hydro Flask looks to have the same blueprint as 321 Strong, Glacier Point, and Fifty Fifty.
Some Redditors explained the source of the many knock-offs of popular h2o bottle brands out there: almost knock offs are but rebrands that come out of the same manufacturing plant as the originals. So we assumed their performance to be the same and avoided testing any rebranded products.
How we tested
There's a lot more that goes into a great h2o bottle than meets the heart! We put our 22 finalists through an all-encompassing series of tests to encounter which would come up out on top. Those tests included:
- Thermal insulation test
- Hot water examination
- Leak and drop test
- Condensation exam
- Usability test
Thermal insulation test
Since drinking room-temperature h2o isn't something near people prefer, we tested every canteen for its power to keep water common cold. For the bottles that were designed for information technology, we tested their ability to keep water hot besides.
Nosotros tested temperatures with an instant-read thermometer so the bottles only needed to be opened for a short amount of time during temperature testing.
Just for good measure, nosotros tested the vacuum insulated bottles equally well every bit the uninsulated bottles with cold water: glass bottles, plastic bottles, collapsible plastic bottles and stainless steel bottles. Starting with cold, 42°F water, nosotros let the bottles duke it out in a temperature controlled room and measured the temperatures along the style.
The cold water in uninsulated bottles rose a whopping twenty°F in the commencement hour and coasted to room temperature after just five hours.
Insulated bottles, on the other hand, fared much better. Information technology took well-nigh 20 hours for all of the bottles to accomplish near room temperature, which is very impressive! This means you can be sipping on water ice-cold h2o throughout the course of a normal 8 or 10-60 minutes day using an insulated bottle.
It's clear from the poor rank of the x-ounce Sigg in this exam that a big cistron in keeping your drink cold is how much water is within. With cold h2o (or ice), the more yous can proceed inside, the amend it will stay cold.
Hot h2o test
Four of our 5 vacuum insulated bottles were suitable for utilize with hot h2o. We tested the Klean Kanteen, SIGG, Hydro Flask, and the Mira bottles. Nosotros added boiling h2o to each canteen, and adjusted water levels until each reached 196°F, then checked on them in even intervals.
We removed the lids and tested temperatures with the same instant-read digital thermometer we used on the cold h2o exam. Hot water returned to room temperature much faster than the cold water did, but these bottles performed according to manufacturer promises.
2018 Updates: 32oz bottle examination
In 2018 we tested our new contenders in some other estrus retention test. This fourth dimension, we picked a standard size (32 ounces) and tested with an uninsulated stainless steel canteen as a control. Water started at a rolling eddy, but by the fourth dimension we pre-filled and blended the water between the bottles to get a fair comparison the average temperature was 184.
In this examination, it was in one case again the narrowest-neck bottle that took meridian position. Unlike the narrow mouth on the Mira bottle from our first lineup, Klean Kanteen's Classic 1.seven-inch opening is broad plenty to fit full-size ice cubes, but it nevertheless gives an edge in insulation performance. 160 degrees after 12 hours is toasty, even on the border of piping hot.
The other standout in this test is YETI, with the heavy (and expensive) Rambler Canteen. If y'all want top insulation with a wide-open oral fissure, YETI was just four degrees lower than the Klean Kanteen after a full twelve hours, compared to more than 20 degrees deviation in the other wide-oral fissure bottles.
Leak and drop test
A bottle that leaks is not much more useful than a lidless cup, and so we tested each bottle for leak potential. Thankfully, none of the bottles leaked with normal utilise and vigorous shaking or twisting, so we decided to do some drop tests to see how they stand up up to some abuse.
We filled each bottle to 75% capacity, so dropped information technology from standing position three feet from the basis on its bottom, then once over again on its superlative, and finally we pushed it off a table nearly three feet alpine.
Surprisingly, all bottles remained leakproof after beingness dropped. All stainless steel bottles dented to some degree, and the uninsulated steel variety dented the worst, causing them to wobble when placed on a flat surface.
Nosotros expected the sport bottles with seemingly delicate flip caps — like the Embrava, Under Armour and the Thermos — to break or at least leak after they were dropped, only they did not. During 1 drop, the Embrava's hat really shifted off the cap threads a flake and took some force to unscrew — all the same it still remained leakproof after existence put dorsum on.
While dropping the glass bottles, nosotros were bracing ourselves for shattered glass everywhere with each drop, yet no bottles ever shattered. The silicone sleeves did a good chore of arresting the drop impact.
Condensation test
Condensation forms on the outside of common cold water bottles because libation air around the bottles can't concord as much moisture as warmer air, causing the moisture to condense. This matters considering it will affect grip on the bottle, as well as potential to damage electronics you're storing in the same bag as your water bottle if enough wet is formed.
Every uninsulated bottle had condensation class on the outside of the bottle when there was cold water inside. Even the glass bottles with silicone covers had condensation form on summit of the covers.
The corporeality of moisture was consistent between the bottles, but varied by day, depending on the humidity. If you plan to transport bottles with laptops or other electronics, the safest selection is to use a vacuum insulated bottle or room temperature water.
Usability test
Each bottle went through usability testing, to run across how it stood upward to regular utilise.
Ice: Nosotros wanted to know if information technology was possible to add ice and how easy it was to add h2o. We used standard ice cubes from a freezer's automatic ice machine. About five of the bottles nosotros tested didn't have mouths wide enough for water ice or for cleaning with brush.
